SUPPORT FOR RUBBER-TIRE VEHICLES.

To all whom it may concern:

Be it known that I, HERMAN FREYE, a citizen of the United States, residing at Nest Orange, in the county ofEsseX and State of New Jersey, have invented certain new and useful Improvements in Supporters for Rubber-Tire Vehicles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will einble others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to figures of reference marked thereon, which form a part of this specification.

This invention relates to a device for suporting rubber tired vehicles, by the edges of the rim adjacent to the rubber, so that when the vehicle rests on the tires for a long time, in one place, there is no flattening effect on the material of which the tire is composed, and in this way the life of the tire is lengthened and the vehicle remains an easy riding vehicle.

This device is applicable to all rubber tired vehicles, whether of the solid rubber type or inflated, but is particularly designed for the solid rubber tired wheels.

In heavy apparatus, such as fire apparatus, and especially in small places or the outlying districts of large cities, the vehicles are not used very much and are apt to stay in quarters a long time and rest on the same spot on the wheels. This flattens the tires at the point on which they are resting, and after a while they become uneven.

The object of this device is to lift the wheel by mechanism within a casing underneath the floor, this lifting being done on the rigid edges of the folly adjacent to the tire, and lift the wheel either clear of the floor, or high enough to take the weight from the rubber of the tire.

Supporters for wheels have been made for fire-houses, and similar places, that are permanently fixed in the floor and project therefrom. These have a disadvantage in that the supporters for the front wheels are apt to cut the tires of the rear wheels when the rear wheels pass over them.

The device herein described operates as a jack to lift the wheel, there being preferably four of these used on a vehicle, that is, one

for each wheel, and when so raised, the weight of the vehicle holds the supporter in place. As soon as the vehicle that is supported leaves the supporter, the supporting plates or strips fall within the casing so that there is a flush surface on the floor, and no obstructions are present when the rear wheels pass over the space on which the front wheels rested. The devices are adapted to be operated simultaneously when lifting the vehicle, but a simpler method is to raise each one separately, and thus not raise the whole weight at the same time, and in this way one operator can lift a wagon or truck easily.

The invention is illustrated in the accompanying drawing, in which- Figure 1 is a side view of a pair of supporters arranged on the front and rear wheels of a vehicle, one being shown depressed or withdrawn so as not to support the wheel, and the other supporter being shown elevated to lift the wheel slightly from the floor. Fig. 2 is a section of the device with the lifting mechanism and the supporting plates in ele vation. Fig. 3 is a similar section, but with the supporting plates shown in section. Fig. 4 is an end view with the operating lever shown in section, and Fig. 5 is a top view of Fig. 3.

The device comprises a casing which has a top plate 10 and depending side plates 11 and a bottom 12. The top plate 10 has flanges 13 which rest in the floor and act to support the device, and the flanges are sup plied withthe perforations l t to receive suitable screws by which the device is held in place. The top plate is also provided with an approximately centrally arranged depression 15 in which the wheels are adapted to ride so that the vehicle can be properly placed before it is raised, and insuring the disposition of the supporting plates of the supporter underneath the wheel perpendicular to the axle.

In the casing of the device are arranged the lovers 15 and 16 which form a toggle, they being pivoted together on the pin 17 and the toggle 16 swinging on a pin 18 secured to the casing and forming the element against which the pressure of the toggle is exerted on one end. The other end of the toggle is secured to a pin 19 arranged in the plates 20 of the block 21. The block 21 has,

- This bar is used as a lever to make the toggles whena wheel fover thesupporter' is to be "raised; "The major portion ofthe travel'fof "an apparatus moving the s'upporti'ngplates and the toggle is easy, P

because the supporting plates have a distance to travel, vertically, before they en gage the portions of the rim to be engaged by them, and when'they do en age the'rimthey are nearly alined and it takes but little pressure on the end of the bar 27 to force the teggl'es into place; The weight "of the vehicle being very much greater than the Weight of the bar 27, the toggle iskept in the position shown in' Fig. and the rim' of' the wheel is kept clear of the floor.

A supporter for wheels comprising a 'casing,a toggle supported therein, parallel supporting plates on the toggle, for engaging a wheel on both sides of its tire, means 'for limiting the movement of the toggle in one direction when-it is slightly out of alinement, and manuallyoperatedfmeans for making thetoggle and normally acting to break the toggle. i

4.
